Original application filed May 25,1905, Serial llo 262,1 2? Divided amlthis application filed December 7,1905. SerialNo. 290.335F

To a, whom it 71mg concern:

Be it knownthat I, SALEM A. BAKER, of Indianapolis, county of Marion, and. State of Indians, have invented e. certain. new and. useful Sliding- Door Construction; and l do hereby declare that the following is a lull,

clear, and exact description thereof, ro

enee being had to the eccompenying drawings, in which like letters refer to like parts.

This application is divided out ol'an appli cation filed. by me May 1905, Serial No. 252,147, for earedoors.

The object of this invention it to provide a convenient means for holding the lower ends of car-doors in place at all times, whether the door he closed or open, to prevent the some from flying outward while the car is moving, thus causing great damage.

To this I end, a vertically-slidable angular belt that is not oscillatory is provided that drops in behind the lower track when the door is closeol end that maybe I ted above Said bolt is also provided witl'i a downward tcnsilim. on. vits lower end that engages the lower track. and limits the outward movement of the door, so thatthe door can swirg outwardly only for enough to permit it to he moved lougitudiiially. This prevents the doors swing-" ins? while a car is moving.

lfhe various features of the invention. will be uhderstood froni the accompanying drawings and the following description. and claims.

in the drawings, Figure. 1 is 9. front elevation of o. car-door provided with "my invention. Fig. 2 is a vertical. trans rse section through. the car-door and adjacent par s ol" the framework, the control port oi the door being broken away and the door being shown in its closed position. Fig. is a similar section. 01" the lower part of the door and lower rail, the door being; partially open or swung out at the lower owl. fl" 4 is a transverse section onv the line l- 4 of Fig. 1 through the ottocln'ncnt to the lower rmrt ol the door for carrying a sliding bolt. l ig. I shows the lower part of Fig. 2 with the doo in its outer position. i

In. detail, ll) lioproseols e stm.=l --oar, and 1 .l is the door. it has honours 11;. supported and llll()"'tl)l0 upon. the upper rail 'l-El. l. secured to the l'rurm: ol' the an by the arms 14. 'lllerc is also o. lowrr track ll}, cal. the arm 16.

pieced.

225 when. the door is moved laterally.

Vertical bolts 17 are slidably mounted in a bolt-holder formed of the plates 18 and 19, that are secured to the door by the bolts and nuts 20. The plate 19 has two parallel flanges 2i, between wl'iieh the bolt 17 is The flanges 21 are wide enough to hold the plate l8 out ol contact with the bolt 17, so that said bolt will be readil y movable vertically. The bolt 17 has a head 23 at its upper end whereby it may be caught by the linger and elevated and whereby the bolt is prevented lron'l escaping downward. Said bolt 17 is bent inward at its lower end to form a horizontal portion 2 and then downwardly cess 26, that is adapted to lit over and ride upon the lower rail 15 when the door is in its outer position. ports is such that when the bolt is in its lower position, as shown in Fig. 2, it will extend below the upper surface of the roll 15.

it is obvious that in its closed position the lower part of the door will be held in against the car by the lower rail 15 engaging the bolts 17. When. it is desired to open or move the door, said bolts are elevated somewhat to the position. shown in Fig. 3, so that they will ride upon the rail 15. in its outermost posi tion. the notches 26 of the bolt 17 willeiigage the upper edge of the lower track and prevent,

the door from moving either outward y or inwardly, but permit the door to be laterally slid able. A flange 30 braces the parts 24. and Thus it is seen that with this belt arrangement the door is prevented from escape at its lower end whether in a. closed or in an open position, end it cannot during the movement of the rain, 'tjvl especially while going obout o. curve or on mg other cars, swim outward and GHgS-fifi cars or other objects.

What l claim as my invention, and. desire to secure by l lot-tors Patent, is

l. The eombimition with. a car lnwirszj IL lower bl'ltfih. for the door thorcolf, and :1 (our slidalrly mounted on, said. car, of a doll; .lnouoted in coimcction with the lower port ol sold door that vertically .niovnlilo ciid not livscillatory and has It lmrimntal inwardly :cxtonding lower portion with a notch on. the

Likewise the relation of the ,end of the main portion of the bolt will engage the track While the door is closed and prevent the door swinging outward and while the door is in its outer position the notched portion of said bolt will prevent the door moving forward and the extreme lower ex tension of said bolt will prevent thexloor moving outward, substantially as set forth.

2. The combination with :1 car liming a.

. portions and turned downwardly at theirinner enris the arren ement being such that the inner clciwnwardTy-extending; portions of said bolts always extend below the upper edge oi seirl truck, and the outer vertical portionv of said bolts will extend below the upper edge of said track when the door is in its innor position, but which may be elevated above said track for permitting the movement outwardly of the lower part of the door, and n groove on the under side of the l1orimotel portion of each bolt adapted to lit over the upper edge of said truck when the door is in. its outer position.

In witness whereof I have horeun to ufiixod my signature in the presence oi the witnesses herein named.
